SSl-l LOCK AND LIFT.

SPECIFICATION forming part of Letters Patent No. 708,406, datedSeptember 2, 1902.

Application filed May 10, 1902.

T0 all whom it may concern:

Be it known that I, CHARLES W. RoBIsoN, a citizen of the United Statesof America, residing at McKees Rocks, in the county of Allegheny andState of Pennsylvania, have invented certain new and useful Improvementsin Sash Locks and Lifts, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in sashlocks and holders, and has for its object to construct a sashlock by theaid of which the window-sash may be supported and looked at dierentpositions; and my invention further aims to provide means whereby boththe upper and lower sash may be supported at different positions andsecurely locked.

The invention further aims to provide means whereby when the sash arelooked with my improvement the device may not be tampered with from theoutside of the window, irrespective of whether the lock may be engagedwhen the sash are in the closed or partially-opened position.

With the above and other objects in View the invention further residesin the novel construction, combination, and arrangement, as will behereinafter more particularly described and then specifically set forthin the claims; and in describing the invention in detail reference isVhad to the accompanying drawings, forming a part of this specification,and wherein like numerals of reference will be employed for designatinglike parts throughout the several views, in which- Figure l is a frontelevation of a portion of a Window, showing my improved device in thelocked position. Fig. 2 is a top plan view of the frame carrying thelocking lever or cam, which in practice is secured to the mid-rail ofthe lower sash. Fig.` 3 is a top plan view of the frame to be attachedto the lower sash, with locking-button or cam-lever removed. Fig. 4 is arear elevation of the member which in practice is attached to themid-rail of the upper sash. Fig. 5 is an edge view of the same. Fig. 6is a transverse vertical sectional view taken on the line 6 6 of Fig. 2.Fig. 7 is a front view of a window, showing the upper sash partlylowered and locked in the lowered position.

I am aware that it is old to provide a locking device consisting of twomembers, one in Serial No. 106,745. (No model.)

the form of a pivoted button or cam-lever adapted to be connected t-othe mid-rail of the lower sash of the window and the other adapted to beattached to the'mid-rail of the upper sash of the window and adapted toreceive the button or cam-lever for locking the upper and lower sashtogether. My invention, however, while accomplishing this also providesmeans whereby the upper or lower window-sash may be respectively raisedor lowered within certain limits and locked in their partially-openpositions, or both the upper and lower sash may be raised and lowered,respectively, and locked in their respective partially-opened positions.

To this end I provide aframe or casting l, which is adapted to besecured to the mid-rail 2 of the lower sash and for this purpose is'provided Vwith one or more apertures 3 to receive fastening-screws,nails, or the like. Centrally mounted on this frame or casting l by apivot-pin 4 is a button or cam-lever 5, which when in position forlocking the sash lies partially beyond the inner edge of the frame orcasting 1, as illustrated most clearly in Fig. 2. This button orcam-lever is provided along the edge which projects beyond the frame orcasting 1 with an upwardly-extending flange 6, extending outwardlybeyond the body of the button or cam-lever at one end of the latter andforming a handle 7. This ilange at its other end tapers off to a pointwith the plane of the body of the camlever for a purpose as willpresently appear.

The frame or casting l near each end thereof is provided with slots S,and mounted on the frame or casting by riveting or like means, as at 9,are springs l0, which are inclined upwardly and then bent downwardly atright angles into the slots and have their free ends turned outwardly toform the stops ll, which engage underneath the frame or casting l, asmost clearly shown in Fig. 6. The shoulders 12 of these springs formstops, against which the handle rests when the cam-lever is in eitherthe locking or unlocked position. In order to prevent the handle movingaround a greater distance than is desired, I provide small stops 14 onthe casting or frame l, as shown in Fig. 2, which will limit themovement of the button or cam-lever, especially when being moved to theunlocked position.

In order to lock the sash at varying positions, I provide a standardwhich in practice is secured to the mid-rail of the upper sash and hasmeans to receive the button or camlever of the member carried by themid-rail of the lower sash. This standard takes the place of the keeperordinarily employed and is of a length sufficient to extend aconsiderable distance above the mid-rail of the upper sash and isprovided at different points throughout with means to receive thelocking-button or cam-lever instead of being capable of engagement withthe button or cam-lever at one position only, as is the case with theordinary keeper. The standard consists of an upright 15, having anapertured base 16, which is secured by screws or like fastening means tothe mid-rail. of the upper sash. For giving the same a neat appearanceon the Window it is preferably tapered toward the top and is somewhatconcavoconvex in form, the concave inner face being toward the inside ofthe window. To the inner or concave face of this standard is secured inpairs a series of shelves 17 18, each shelf 18 being provided with adownwardly-extending projection or lug 19. These standards will ofcourse be most cheaply manufactured by molding, and in practice I havefound that in order to cast the standard with the shelves it isnecessary to provide openings 2O in the standard, so that the same maybetapped in under the concave face.

In Fig. 1 I show a fastening device 21 at the bottom of the lower sash,so that the latter may be fastened down and locked, and the upper sashmay be lowered a desired distance and locked with my improved device, aswill be apparent.

The lock is shown in Fig. 1 in position for locking the two sashtogether, and when it is desired to disengage the lock the spring 10 isdepressed, so that the button or cam-lever may be moved around on itspivot-pin and swung around to the reverse position to that shown in Fig.2. As the handle passes over the other spring 10 it depresses the sameuntil it has passed beyond such spring, when the latter returns to itsnormal position and holds the button or cam-lever in this unlockedposition, the said button or cam-lever being prevented from furtherinward movement by engagement with the stop 14. In the locked positionthe button or cam-lever passes between one of the shelves 17 and theadjacent shelf 18, with the iiange 6 back of the projection or lug 19and the handle lying behind one of the springs 10, as shown in Figs. 1and 2. With this construction it will be observed that the upper sashmay be low-y ered and locked at various positions, according to thenumber of places provided for locking engagement of the button orcam-lever with the standard. It will also be observed that the uppersash may be lowered a slight distance and the lower sash raised a slightdistance and both sash locked in their partially-opened positions.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a device of the type set forth, the cornbination of a standardsecured to the mid-rail of the upper sash, with shelves arranged inpairs on the standard, each alternate shelf having a downwardlyprojecting flange, a frame carried by the mid-rail of the lower sashwith a cam-lever pivotally mounted on the frame, and a iange carried bythe camlever, the under face of the cam-lever engaging and guided by oneof said shelves, the flange of the succeeding shelf engaging the iiangeof the cam-lever, when the latter is in its locked position, and meansfor automatically locking the handle of the cam-lever, when the latteris locked to the standard.

2. In a device of the type set forth, the combination of a standardsecured to the mid-rail of the upper shelf and carrying engaging means,a frame mounted on the mid-rail of the lower sash, with a cam-lever,pivoted to the frame, depressible means secured to the frame and adaptedto engage the cam-lever and means on the casing to limit the movement ofthe camlever,whereby the latter may be locked between the last-named andthe depressible means.

3. A device of the type set forth,comprising a standard secured to themid-rail of the upper sash and carrying engaging means, with a framesecured to the mid-rail of the lower sash and having a cam-lever pivotedthereto, said frame having openings formed therein, with springs securedto the frame and inclining upwardly and having their ends bentdownwardly and outwardly, with the outwardly-bent portion engaging theunder side of the frame adjacent said openings thereby limiting theupward movement of the spring, and stops carried by the casing, with thehandle of the cam-lever adapted to be received between said stops anddownwardly-bent portions of the springs.

4. A device of the type set forth, consisting of a standard secured tothe mid-rail of the upper sash, with engaging means thereon, a framehaving openings therein and carrying a pivoted cam-lever with a handlethereon secured to the mid-rail of the lower sash, de-

pressible means carrying shoulders secured to the frame and operating inthe said openings with stops carried by the frame, the handle of thecam-lever when actuated depressing said depressible means and beinglocked between said stops and the shoulder of the depressible means.

In testimony whereof I affix my signature in the presence of twowitnesses.
